摘　　要：依托地锚式城市景观悬索桥实例工程,对地锚式悬索桥按照自锚式悬索桥体系转换的施工方法进行监控,采用MIDAS/Civil有限元软件进行理论计算,结合实际监控数据进行对比分析。监测结果显示:1)一期状态索塔顶偏移量与设计位移偏差均不大于1.0 cm;索塔最大沉降值为-6.38 mm。2)在张拉调索体系转换过程中,索力实测值与理论值的偏差逐渐减小;全桥吊索内力分布较为均匀,主缆实测索力与理论值偏差均在10%以内。The ground anchor suspension bridge was monitored,which was constructed according to the system conversion method of the self-anchored suspension bridge. The finite element software MIDAS/Civil was used for theoretical calculation,and the calculation results were compared with the actual monitoring data. The displacement deviation of the tower top was not more than 0. 01 m compared to the design value,and the maximum sedimentation value of the tower was-6. 38 mm. The deviation between the measured value and the theoretical value of the cable force was gradually reduced during the system conversion. The measured value and the theoretical deviation of the main cable force are within 10% and full-bridge suspender force distribution was uniform.
